Specification of Letters Patent.

Patented Nov. 1'9, 190?.

Applieation'filed March 14.1907. Esau... 362.423.

To all wlwm it may concern:

Be it'known that we, EDMUND H. LUnKEN and CHARLES M. CoNKLIN, citizens of the United States, residing at Cincinnati, Ohio,

have invented-certain new and useful Im;

improvements are applicable in the main to eit er sliding or swingingsashes, although in the present drawing they are shown as embodied ma sliding sash designedwith particular'reference for use in connection. with fire proof windows, such as shown and described, for example, in the application filed by us Nov. 22/06, 344643, although of course not limited to use in connection with such window frames.

Among the objects of the invention are to provide an improved construction of sash which will be very compact, will be strong and rigid at the corners, will present an extren ely neat arid finished appearance, and

the upper and lower sash, the ,ce'ntral portion ner stripsll are formed of the shape shown will permit of the ready insertion and removal of the glass.

With these and other objects in view, the invention includes the various features of constr'uetion and arrangement and combination of parts hereinafter described and partieularly set forth inthe appended claims.

An embodiment of the invention is illustrot-ed in the, accompanying drawings, in which 3- Figure 1 is a sectional elevation of both of each being broken away. 2 is a front elevation of the lower'sash. Fig.3 is a part horizontal section on line 3-3 of Fig. 2.

Fig, 4 is a perspective detail of the upper left-hand corner ofthe lower sash. Fig. 5 is a perspective detail view of the corner block for the Tower sash to which the sash cord is' connected. Fig. 6 is a side elevation of the same partly in section. Fig. 7.1s aperspective viowfiof the upper portionoi one of the I p I guides are conveniently made of-prcssdguide strips removed. Fig. 8 is a section on line 88 of Fig. 2.. detail of the corner block'for the upper sash.

The sash shown in. these drawings conipriscs outer stri )s H) and 10'" and inner strips ll and- 1]. T :c outer strips are of )lane metal, as also is tluinner strip 11. TI 10 in- F ig. l) is a perspective .strong integral connection.

' strips'10 in any suitable manner, as by'riveting, strips of asbestos, or similar material, being preferably interposed as shown at 11*. The strips or platesLO and 11 are niitcred at the lower corners and the abutting edges secured together by welding to produce a The side strips. or plates 11 are shown as carried straight to the top of the sash and to their inside edges at the top are welded the ends of the cross strip or plate 11. The strips or plates 10 however are shown as cut shorter by an amount equal to -the width of the cross plate or strip 10 so that this latter extends the en tire width of the sash and has its lower edges adjacent and welded to the end edges of the side strips 10.

Iii the space provided between the str'i,-

11 and the corresponding strip 10 is locate a removable bar 13 which is' referably of channel shape and is removabl lace by bolts 14 as shown. The removable liar is located onthe upper edge of the lower sash as shown in Fig. 1-. The upper sashis constructed'in substantially the same man nor as is the lower, but is reversed-inposition, the removable bar 13 being'in this instance on the bottom of-thesash, as also shown in Fig. l. A spring weather strip is rovided on one of the -rneeting rails, of the ibrm shown in said figure and is secured in place bythe-bolts The glass occupiesthe space between the portion or'llanges 11* and the strip or plate 10, while in the channels at the-sides of the sash formcdb'y flanges 11 and the strips 10 -are located the removable guides 15. These consist preferably .of metal strips having substantially V or wedge shaped.portions. 1.5- and parallel portions 15" which lie we; tween the side walls ol the channel. These y secured in .30

steel, and in order to form a non-corrosive bearing-surface they are preferably cnvel oped in a thin sheet. olspring brass, as indi-- 'catedat 1(3, tho ends beingcontinuedi'n and curved toward {.rfacb other to boar agaiilst'the prevents the inside a'linished appearanceyt-he channels formed by inwardly struck portions 11 2 are closed by ornamental strips 17, which have parallel flanges or walls 17 extending window frame. In ord ir to givethe sash on and resting against thebottom of the ehan nel formed byinwardly 'struck portions.

by the-plane back strip 10, which forms an integral part of the back frame and channeled front strip 1-1 forming an integral part of thefront frame,- these two being secured together in the same manner as by rivets 12,

with an interposed asbestos strip and the glass panes being seated in the grooves or .channels formed by'the parallel portions or flanges. The central channel formed by the inwardly struck portion of the strip 11 is 'closed by a similar molding strip 17. a The channels at the bottom of the lower sash and at the top of the upper sash are provided wi h spring strips 18, preferably of brass, suitably secured in the channels and-having rounded portions 18* which are designed to engagewith the ribs or beads-19 secured at the-top-and bottom of the window frame, as indicated in dig. 1. It is desirable that one of the guides 15' at least should be removable longitudinally so as to ermit the sash to be removed from the win ow frame.

videa very-simple means for effecting this and also for connecting the sash cord, as shown in Figs. 4, 5 and 6. This comprises a corner block20 havin a vertical portion of a suitable size to fit in the channel between the flanges 15"- of the guides. One of these -flanges is provided with a cut-away port-ion as indicated at 15 in F1" 7, and the-corner vblock has a corresponding projection Z0 (Fig 5) which fits in this cut-.aw'ay portion when the parts are in the position'sliown "Fig. 4-. The corner block has a transverse opening 21 through whichv the end of the sash cord .22 fpasses, the opening having rounded edges on the outside to prevent wear of the sash cord and a counter-sunk portion on the insidc'to receive the knot of the sash cord as indicated at 23. After the arts are assembled in the position shown in *ig. 4, they are held together by a set screw 24'passnn through the lla-nge 11" and engaging tlle lilock which prevents movementof the block, and the block by reason of its I shoulder. or enlargemcnt 20 engaging the cut-away )or'tion 15 of the guide likewise ongi'tudinal movement of the guide but does not interfere with the lateral movement of same. When, however, the guide is to be removed, upon the taking out of the screw 24, the corner block and guide may be moved longitudinally out of the groove onchannel by simply pulling upon Te pro-- i 1110( iiied, as shown in Fig. This modifi- 'here it is desired to use more than one I glass in a single frame we provide a muntin, as shown in Figs. 12 and 8, this being formed ,said frames for retaining the window frame.

It is desirableto provide means for securing a tight joint between the meeting rails. A very desirable form of means for accomplishing this is shown in Fig. 1 and comprises metal weather strips, preferably of non-corrosive metal such as brass. One of these, 27 for example is constructed and applied so as' tov be capable of spring or yield ing action. it has a flat or plane ortion secured to the meeting rail of the ower sash and a rounded or curved portion spacedl'rom'th'e rail to permit yielding or spring action. .The other strip 28 is secured in a similar manner'to the meeting rail of-the upper sash, but its inclined or curved end need not be spaced from the. meeting rail as a springer yielding action in one strip is sufiicient'. i f What. we claim is:
